What in the world?
100
Also known as idle, or unused, capacity
What is Slack?
100
Define the Problem; Identify the Alternatives; Determine the Criteria; Evaluate the Alternatives; Choose an Alternative
What are the 5 Steps of Decision Making?
100
An equation or inequality that rules out certain combinations of decision variables as feasible solutions.
What is a constraint?
100
When the value of the output cannot be determined even in the value of the controllable input in known, the model is . . .
What is stochastic?
200
The process of identifying a difference between the actual and the desired state of affairs and then taking action to resolve the difference.
What is Problem Solving?
200
Representatives of real objects or situations which can be presented in various forms.
What is a model?
200
A controllable input for a linear programming model
What is a decision variable?
200
A physical model that does not have the same physical appearance as the object being modeled.
What is an analog model?
300
The term generally associated with the first five steps of the problem-solving process.
What is Decision Making?
300
Factor which affect both the objective function and the constraints
What are uncontrollable inputs?
300
A variable added to the left-hand side of a less than or equal to constraint to convert the constraint to an equality. The value of this variable can usually be interpreted as the amount of an unused resource.
What is a slack variable?
300
When all constraints in a linear program are expressed as equalities.
What is standard form?
400
A solution that satisfies all the constraints.
What is a feasible solution?
400
The volume at which total revenue equals total cost
What is the breakeven point?
400
The situation in which no solution to the linear programming problem satifies all the constraints.
What is infeasibility?
400
A linear program is said to be infeasible if the number of solutions that satifies ALL constraints is this number
What is zero?
500
Controllable inputs which are the decision alternatives specified by the manager
What are the decision variables?
500
A decision alternative or solution that does not satisfy one or more constraints
What is an infeasible solution?
500
A variable subtracted from the the left-side of the a greater than or equal to constraint to convert the constraint into an equality. The value of this variable can usually be interpreted as the amount over and above some required minimum level.
What is a surplus variable?
500
A constraint which does not affect the feasible region -- it can be removed from the problem without affecting the feasible region.
What is a redundant constraint?
